Spiderman, whose mass is 72.0 kg, is dangling on the free end of a 11.4-m-long rope, the other end of which is fixed to a tree limb above. By repeatedly bending at the waist, he is able to get the rope in motion, eventually getting it to swing enough that he can reach a ledge when the rope makes a ? = 60.8° angle with the vertical. How much work was done by the gravitational force on Spiderman in this maneuver?
